CASTLE ROCK - "Duck Dynasty" stars Phil and Willie Robertson took a break from filming their A&E reality show to help The Rock Christian Academy raise $60,000 during a recent appearance in Colorado.

An estimated 2,000 people attended the event in which the Robertsons talked about their TV show, family and faith. Fans often cheered or gave them standing ovations during their appearance. Phil Robertson even gave a bird-calling demonstration, and Willie helped display items and provided commentary during the live auction.

The school, which opened in 2008, has 86 students from pre-school to the fourth grade. However, after the Robertsons' appearance, enrollment had already increased to 106 for next year. It plans to use the money raised from ticket sales and the auctions to help fund scholarships, expand the existing school building by 10,000 square feet, revitalize the playground and update technology. It plans to add a fifth grade next year.

Parent-Teacher Fellowship Assistant Director Michael Brumbaugh had the idea to bring the Robertsons to Castle Rock.

"We wanted someone in line with our Christian values, and that's exactly what we got," he said in a news release.

Some volunteers and others in attendance at the event wore camouflage in honor of the Robertsons. One volunteer, John Swanigan, even sported a beard reminiscent of the reality show stars.

After the Sunday evening event, Willie Robertson, president of Duck Commander Co., said he and his father, who founded the company in 1973, were heading back to Louisiana immediately so they could continue filming their popular show the next day. Willie Robertson said the appearance in Colorado was an opportunity to promote their family and faith platform. Phil Robertson added the "school is what our founding fathers envisioned."
